Description
Technical field
The utility model relates to the device technique field of ball screw transmission, is specifically related to a kind of new pattern rolling ball lead screw transmission cooling unit.
Background technique
The ball screw drive mechanism is used very extensive in various machineries and industrial automation field, vertical-horizontal type machining center, the various driven off by shaft machineries of straight line that need such as upright crouch numerically controlled lathe, gantry Machining Center, industrial robot, electroplating equipment wielding machine, panel beating machinery, woodworking machinery, abrasive machine etc. are all using the ball screw drive mechanisms in a large number, and are requiring more and more higher to transmission speed and precision stability now.But nut steel ball and lead screw ball track frictional heating during owing to the ball screw transmission, the screw mandrel thermal distortion that causes prolongs (average temperature rising once every meter long screw mandrel will prolong 0.009mm) makes the Location accuracy of transmission and repeatability very unstable, especially in the long-time high speed transmission application, Location accuracy and repeatability deviation are bigger.Existing international and domestic tradition solves because the screw mandrel heating causes Location accuracy and the unsettled method of repeatability roughly to adopt pre-pull-up structure of screw mandrel and screw mandrel hollow cooling structure, but the both has self narrow limitation and deficiency: one. adopt the pre-pull-up structure of screw mandrel, promptly when screw mandrel normal temperature attitude with its pre-elongation, prolong to remedy the screw mandrel temperature rise.This structure is generally to adopt more a kind ofly, and its intrinsic defect has 1. screw mandrel prestretching values to have that its numerical value is fixed value behind certain limit and the prestretching, can not eliminate the thermal expansion coefficient of screw mandrel fully.2. the screw mandrel prestretching need apply bigger pulling force on the screw mandrel bearings at both ends, causes bearing heating serious, and bearing damages easily.Two. adopt screw mandrel hollow cooling structure, promptly adopt the screw mandrel of hollow cooling, reduce the screw mandrel temperature rise by forcing cooling screw mandrel body; This structure adopts more on high-end devices, effect is also quite a lot of than prestretching, but its intrinsic defect is also arranged: 1. after the cooling of screw mandrel body, more than length is controlled its diameter of while and also will dwindles, this just causes the gap between screw mandrel and the nut to strengthen the instability that makes the repeatability change; 2. owing to the restriction of drive mechanism, the hollow cooling can only make cooling effect not good from the end turnover cooling medium of screw mandrel.3. screw mandrel hollow makes screw mandrel integral rigidity variation.Hollow screw mandrel complex structure, difficulty of processing is big, user cost is high.
Summary of the invention
The purpose of this utility model provides a kind of new pattern rolling ball lead screw transmission cooling unit, its simplicity of design, low cost of manufacture, be easy to produce in batches, Applicable scope is extensive, promotes the stability of screw mandrel transmission accuracy after the use significantly, easy for installation, user cost is low, long service life.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises bearing 1, support end bearing support 2, motor-end bearing support 3, motor cabinet 4, leading screw 11, coupling 12, motor 13, and it also comprises coolant jacket 5, seal ring 6, feed screw nut's seat 7, feed screw nut 8, cooling chamber 9 and heat-conducting glue 10; The middle part of leading screw 11 is connected with coolant jacket 5 by feed screw nut's seat 7 and feed screw nut 8, and two ends, coolant jacket 5 outer ring are provided with seal ring 6, are provided with cooling chamber 9 between feed screw nut's seat 7 and the feed screw nut 8, and feed screw nut 8 outer ring is provided with heat-conducting glue 10.
The outer installment of described cooling chamber 9 has filler opening and oil outlet.
The utility model is to adopt low temperature refrigeration oil to enter cooling chamber 9 by filler opening 14, cold oil flows in coolant jacket 5 and reduces coolant jacket 5 temperature and take away heat, deep fat is discharged from oil outlet 15, the coolant jacket 5 of low temperature reduces feed screw nut 8 temperature by heat-conducting glue 10, takes away the heat that screw mandrel 11 motions produce.
The utility model simplicity of design, low cost of manufacture is easy to produce in batches, and Applicable scope is extensive, promotes the stability of screw mandrel transmission accuracy after the use significantly, and easy for installation, user cost is low, long service life.
